The Corp of Engineers has stopped shad counting at The Dalles, starting this year (2011) on the advise of the Fish Passage Operations and Management (FPOM) committee, made up of NOAA, CRITFC, ODFW, WDFW, IDFW, BPA, and COE biologists.

1)Since the year 2006, Priest Rapids Dam jack counts have included mini jacks.

3) Steelhead counts appear
higher at Lower Granite Dam because most years a group which migrated into
the river system between October and December overwinters below LGR and continues
its migration in early March.

4)As the Army Corp of Engineers
no longer collects adult counts from the PUDs, we now get data directly from
Chelan, Douglas and Grant Co. PUDs and DART.

5)
Wild steelhead are a subset of steelhead. Wild steelhead are counted separately from hatchery steelhead at Corps dams on the Columbia and Snake Rivers. Wild steelhead are identified as fish with an intact adipose fin. However, a small number of hatchery fish may not have had their adipose fin removed.

6)
Shad are typically not counted at any of the Corps dams after August 31 each year and shad are not counted at all Corps dams. An n/a in the shad columns at Bonneville Dam and Lower Granite Dam after August 31st means that the shad are not being counted.

When the source column on this report reads 'unknown' or 'ceftp', it is because the counts have been gathered via the phone or ftp and are considered preliminary data. When the Corp of Engineers finalizes the counts and posts them on their website the source reads USACE.

In 2012, the U.S. Army Corps of Engineers and NOAA Fisheries are currently developing automated counting systems for Lamprey Passage Structures (LPS) installed at Bonneville Dam. In the interest of publishing accurate counts, LPS counts will not be publicly posted in-season until the automated systems are fully operational.

This
report includes adult counts for only the traditional, direct observation
reporting dates.
This information is still preliminary. The table below lists the traditional
or historical dam reporting dates.

The reporting dates table
shows that several dams stop counting fish around November 15th each year.
After a dam stops
counting fish for the season, only the total number of fish are shown on this
report.

These data are updated
periodically throughout the day. The FPC data retrieving robot searches the
web for updated data every 30 minutes in the AM, and every hour in the PM.
